Columbite - well-formed prismatic crystal
stock #23.1-334-(D5924)
Rio Doce District
Minas Gerais, Brazil
3.8 x 2.7 x 2.2 CM (miniature)
price: $550
Pre Tucson

Unusually sharp, lustrous (for Columbite) and perfectly terminated, this is a choice single crystal of the specie. Ex University of Delaware Museum, the condition is outstanding especially given the fragility of Columbite. A heavy piece (just over 74 grams despite the small size), a textbook perfect example from the Brazilian pegmatites of Rio Doce.

Adamite - classic pinwheel clusters
stock #9.1-018
Mina Ojuela, Mapimi
Durango, Mexico
4.5 x 3.8 x 2.7 CM (miniature)
price: $650
Pre Tucson

Very fine light yellow-green crystals of Adamite arranged in the "pinwheel" type of radiating spray. A choice miniature in excellent undamaged condition from the classic finds about 20 years ago at Mina Ojuela. Good Mexican Adamites were once rather plentiful but this quality and form were never common. These are now quite hard to find and this is an especially elegant and esthetic piece. The radiating sprays exceed 2 CM across, these contrast with the gossan matrix. Displays well from most any angle, and the matrix is not the ultra fragile, crumbly type.

Zinkenite on Siderite - old French classic
stock #23.FC-017
St Pons
Alpes-de-Haut-Provence, France
8.9 x 6.8 x 4 CM (cabinet)
price: $1850
Pre Tucson

Superb specimen from the old discoveries at Saint Pons (France). Zinkenite from France is highly regarded and only the newer find in Bolivia about 20 years ago was of the same caliber. This specimen is outstanding for the specie and the locality. Crystals to about 3 CM in length show bright metallic luster and contrast well with the golden Siderite crystals. This association was only found (to my knowledge) in the St Pons discovery. The style, habit and look of these specimens is unlike any others. Such specimens are almost never available and only come from old collections or museum trades which are now very rare. This is the best St Pons Zinkenite I have seen for sale.
